We look at the division of 348881 by 3 
The aim is to understand the frequency of 3 in 348881.

Advancing to step 1:
3 divided by 3 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 3 from 3 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 3

Going ahead to step 2:
If we divide 4 by 3, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 3 away from 4, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 3

On to step 3:
3 goes into 18 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 116.0
If we take 18 away from 18, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

Going ahead to step 4:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 1162.0
If we take 6 away from 8, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 3

Going ahead to step 5:
If we divide 28 by 3, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 11629.0
Subtracting 27 from 28 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 3

Advancing to step 6:
When dividing 11 by 3, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 116293.0
Subtract 9 from 11 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
20 divided by 3 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 116293.6
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
3 goes into 20 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 116293.66
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 116293.66 with a balance of 0.002.
